My Sub Zero fridge suddenly started making a loud, horrible "burring" noise. Of course it was Friday night, and the fridge was full of food ... we had to turn it off because the noise was so bad. We took a chance and called Sub Zero Fridge Repair Toronto and spoke to Jessie. We turned the fridge on, so that he could hear the noise. He immediately said that there was something in the freezer that was interfering with the operation of a fan. We opened the freezer, re-arranged some of the food, closed the freezer and the noise stopped like magic. Several hours later, the fridge is still operating without any noise. We can't say enough about Jessie expertise in diagnosing the problem without even seeing the fridge! We will be sure to contact Jessie again whenever we need service on our Sub Zero.
